Robust Spectral and Energy Efficiency Tradeoff for RIS‐Aided Multi‐User Communication
IET Communications, Volume 20, Issue 1, January/December 2026.In this work, an RIS‐aided multi‐user network with imperfect CSI is investigated. Correspondingly, we focus on balancing SE and EE through the collaborative design of the base station (BS)'s precoding matrix and the RIS's phase shifts, which consider the transmit power budget and the channel uncertainties constraints.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

DRL‐Based Joint Clustering and Trajectory Optimization for UAV‐Assisted Emergency Networks
IET Communications, Volume 20, Issue 1, January/December 2026.6G is expected to see unprecedented data traffic surges. UAV‐assisted MEC aids emergency communications but faces challenges from dynamic user mobility and heterogeneous tasks. To address these, the proposed KM‐PPO integrates interference‐aware k‐means clustering (for user aggregation and initial UAV deployment) and PPO (for stable policy updates and ...
